This is a very simple and almost too obvious design that is perfect precisely because of its simplicity. The greater lifting advantage of the 7:1 lift ratio pulleys require just 22 lbs (a little more for the Unlimted hardtops) of effort to raise the 150 lb. Jeep Wrangler hardtop. The gear ratio of the Brake Winch requires even less effort at the handle. Your hardtop can be suspended indefinitely even in the electric system.
